Quasimaps and some examples of stacks for everybody
Rachel Webb
TL;DR
This paper introduces the theory of quasimaps to GIT quotients, providing intuition, concrete examples, and a closed formula for the quasimap I-function, while illustrating general stack concepts.
Contribution
It offers an accessible introduction to quasimaps and presents a closed formula for the quasimap I-function with illustrative stacky examples.
Findings
Derived a closed formula for the quasimap I-function
Provided concrete examples of stacks and quasimaps
Clarified stacky concepts through practical illustrations
Abstract
This note introduces the theory of quasimaps to GIT quotients with intuition and concrete examples, with the goal of explaining a closed formula for the quasimap -function. Along the way, it emphasizes aspects of this story that illustrate general stacky concepts.
